I have a file with a pattern that repeats throughout the file:

LABEL text text
text text text
text text text
LABEL
more text

(where LABEL is identical throughout the file)

and need to parse it so that it produces everything after each instance of
LABEL (delimited by the next instance of a label) on 1 line :

i.e.

LABEL text text text text text text text text
LABEL more text

etc etc

Thanks in advance

Don't make a big deal out of everything; just deal with everything.

or by the end of the file apparently

awk -v RS="LABEL" 'NR>1{$1=$1rint RS,$0}' file

1. Put LABEL in its own line, using 'tr', 'sed', whatever

2. Then, you have nice line range to work with. Use 'tr' to collapse
the lines and whitespaces.

If you're adventurous, then you can try my C extensions to Bash.

strcpy all < file
for i in ${all|,LABEL}; do
echo "LABEL ${i|.strip}"
done

See my .sig below.
